The right humanity immerses in the heaven of heavens which oneself creates, forgets oneself, just like the astronomy expected many times such as well as the Earth history once performed the dissimilarity, came from the nameless interspace because the instantaneous interspace erupted the volume giant planetoid which formed, was raiding by the extremely high speed to our sky-blue Earth, moreover the track probably passed through the precise trajectory computation to resemble, 100% collisions to the Earth, launched in the entire human history the only globalization uniformization integration to save Earth's great campaign from this, but after all turned danger into safety, the humanity more and more discovered, each other was such is familiar with such need each other, therefore humanityAfter separates mutually repelled mutually has conquered mutually for several million years, finally under the rational impel has realized the final return unification, from this time on also did not have the language, the custom, the belief difference again, again also did not have the region, the skin color, consciousness barrier, the humanity finally to construct belonged to each earthman's Earth to unify the extremely happy heaven!

正当人类沉浸在自己一手缔造的极乐世界中，忘乎所以的时候，正如多次天文预料的那样以及地球历史曾经上演的一样，一颗来自无名星际间由于瞬间的星际爆发所形成的体积巨大的小行星，正以极高的时速袭向我们蔚蓝色的地球，而且轨道好像经过精确弹道计算似的，百分之百的撞向地球，由此展开了整个人类历史上唯一一次全球化一致化整体化拯救地球的伟大战役，而当一切都化险为夷之后，人类越来越发现，彼此是这样的熟悉这样的需要彼此，于是人类在互相分离互相排斥互相征服了几百万年之后，终于在理性的感召下实现了最终的回归统一，从此再也没有了语言、风俗、信仰的差别，再也没有了地域、肤色、意识的障碍，人类终于构建成了属于每一个地球人的地球统一极乐天堂！

The first procedure uses the GAMIT software to estimate parameters such as station position and orbital trajectory on a daily basis for a given 24-hour interval from the union of three data sets:(1) the campaign stations,(2) the continuously operating GPS stations in Antarctica,(3) long-running continuous GPS stations around Antarctica. In the second procedure, we combine the daily solutions with global GPS sub-networks (IGS1, IGS2, IGS3), which is provided by Scripps Institution of Oceanography, using the GLOBK software in a "regional stabilization" approach in order to estimate the positions and velocities.

数据处理分为两步，第一步：运用GAMIT软件进行单天解算，估计站位置、轨道等参数，其数据源主要有以下三类：(1) SCAR GPS观测站；（2）南极的连续跟踪站；（3）南极及其周边的部分IGS站；第二步：运用GLOBK软件加入SOPAC（Scripps Orbit and Permanent Array Center）的全球GPS子网（IGS1、IGS2、IGS3）进行全球网平差解算测站位置和速度。

In this way, the velocity inverse of a manipulator at singular configurations is uniquely defined, hence, the precision trajectory control of a manipulator at singular configurations can be implemented.

The results show that under the complicated upper limit control logic,the upper limit depth trajectory is not a simple form,but two or more irregular forms of re-entering into the upper limit depth,or regular oscillation form around the upper limit depth.These results may be expected to provide a theoretical basis for analyzing the problem in sea trial.

仿真结果表明，在复杂的上限控制逻辑下，上限深度弹道不是一种形式，可能存在不规则的2次或多次再进入上限的弹道形式，或者存在上限附近深度规则振荡的弹道形式，这些规律为实航中出现的一些特殊现象分析提供了理论依据。
